I've posted and linked to numerous videos of savants on this page, but Orlando Serrell is a very unusual case. He wasn't born a savant, and only became one after being hit in the head with a baseball when he was 10.

Since then, he can recall any day of the week for any given date, but on back to the date of the accident. He can also recall the weather in Virginia on that day!

The video also includes footage of Orlando undergoing an MRI scan, and an interesting analysis of the results.
